300pcs 22mm Seal Cap Liner Leakproof Adhesive Foam Safety Flask Seals Best for Cosmetic Bottle/Jar Cap Liners Tamper Seal Cap

it comes in handy we use it for the we cruses and it work perfect

Worked great on a shampoo bottle filled with booze.

I would say about 30% of them didn't really adhere to the bottles I had but the other 70% did work though not very securely (very easy to peel off)

22m cappers / safety seals are perfect for the narrow tops of the small, quarter pint medicine bottles they sell here on Amazon. I buy/ use the Mahogony colored classic colored plastic medicine bottle that fills up to 100 ml's and is a quarter pint, or meant for a quarter pints capacity when filled up to the 100 line...The other side of the bottle has lines for by the OZ and goes up to three and a half, Surpassing the 100ml line which I had always assumed was the top and a 4 pint total, but apparently if the OZ measurment is correct a hair above the 100ml line is about 3 and 1/2 ounces...If you fill the bottle all the way to the "neck" or where the lines come to a stop just a little passed the 3 and 1/2 ounce line where the neck of the bottle begins to narrow, then you have yourself a solid 4 ounces in the bottle, just figured that out today, so apparently I have been capping 3 and 1/2 ounces or a few ml's less than that and calling it 4 ounces, now everything makes sense because with my recipes, I would always come up with a few more bottles than I thought I should have, I always just assumed I got my calculations on the amount of ingredients wrong, but I have been correct the whole time and that is a good feeling to know...anyway these tings are amazing and if you are serious about making your own medicine like I am, the only professional way to do it is with a capper/ safety seal, even if you are the ony one using them, it is satisfying to pop open the safety seal and go through the whole process, if you give it to someone elsewho comes down with the cold or a cough and needs some medicine or cough syrup, then they will have the added benefit. peace of mind that comes with buying a freshly capped product, the feeling that your medicine, knowing that has not been tampered with, is very important to everyone, or should be. If you use these, and get them in the right size depending on your bottle, use a ruler or some sort of measurement tool if you are unsure to get the diameter, then order the tightest fitting but not to tight/ too little ( I ordered some 20mm ones just in case 22 was too big, but it turned out 22 was the perfect size and 20 would be too small and slip and fall off into the bottle, not what you are looking for, these are the perfect size to fit the cap cover it completely with just the slightest lip from where the user/ he or she who opens it can use their fingers and or finger nails to get the safety cap off easily, but not too big that you cannot screw on the white plastic top. Perfect size, perfect fit, perfect product, a must have if you are going to be making your own medicine/ or elixers and want to be professional about it, people will be wowed by your attention to detail...
